Specification forming part of Letters Patent No. I 82,4122 dated September 19, 1876 application filed i August 21, 1876.

To all whom it may concern:

Beit known that we, SAMUEL G. DIKE and SIDNEY M. BROWN, of You Bet, in the county of Nevada, and State of California, haveinvented a new and Improved Flume, of which the following is a specification;

Figure 1 is a perspective view. Fig. 2' is a side elevation. Fig. 3 is a plan of the sandbox and upper portion of the flume.

Similar letters of reference indicate corre- This invention relates to that class of flumes or chutes which are used for conveying lumber, wood, 850.; and it consists of a sheet-met al trough, made up of semi-cylindrical sections, supported on trestle-work or other suitable support, and provided at its upper end With a box for the deposit of sand, and at its lower end with a grating for separating the wood, lumber, &c., from the water.

. A is a semi cylindrical flume or chute, made from sheet-iron, of suitable thickness, riveted or bolted together, forming sections of convenient size for handling. The sheet-iron sec tions are placed on timbers or plank B, in which semicircular recesses or notches are out, which fit the exterior of the chute. These supports may rest upon the natural earth, or

and gravel, which would without it. pass into' and obstruct the flume. This box is provided with an inlet, a, and an outlet, b, near the E, that is provided with the grating or'curved bars d, for separating the lumber, wood, or other articles that may come down from the flume.

Water is admitted 'to the box D, which is of such size as to permit the subsidence of the heavier foreign matter. Wood, lumber, or other articles to be transported are placed in l the upper end of the flume, and are carried along by the current, and delivered on the grating 'at the lower end of the flume.

This flume is easily moved from place to place, and can be readily set up for operatioln Where water is available, it affords a most economical means of transportation. This flume is especially adapted to rough country. It may be protected against corrosion by paintiug or coating it with coal-tar.

Having thus described our invention, we clann as new and desire to secure by Letters Patent-- A flume composed of semicylindrical sheetiron sections, placed upon suitable supports, and provided with a sand-box at its upper end, and a curved grating at its lower end, and a walk at one of its edges, all constructed and arranged as herein shown and. described.
